Abstract—

Results from elaborating methodical approaches to assessing the technical state of boiler units based on quality indicators, including assessments based on two groups of indicators—environmental safety and technical and economic efficiency—are presented. The procedure of assessing the technical state based on the considered indicators is given. The main indicators (parameters) of boiler units determining their environmental safety and characterizing their technical effectiveness and economic efficiency are presented. The weighting coefficients of indicators that reflect the extent in relative units to which each individual indicator influences the technical state are given. The basic indicators (basic values of boiler unit parameters) with respect to which the technical state of units is assessed are suggested. Technological standards for specific emissions of harmful substances into the atmosphere are adopted as the basic values of indicators determining environmental safety. For the indicators of technical effectiveness and economic efficiency, it is possible to take the standardized values reflecting the actually achievable technical effectiveness and economic efficiency of the operating equipment or the target values of indicators determining the modern and prospective technically achievable requirements for equipment. Point and indexed assessments of state are considered; reference values of score assessments are pointed out, and functional dependences for carrying out point and indexed assessments of state are given. An interpretation of the assessment system with determining the technical state levels is given, using which it is possible to establish a correspondence between the considered quality indicators and existing standards for harmful emissions and to determine the ability of equipment to perform its prescribed functions. Depending on the values of technical state indices, versions of technical measures taken for the main equipment and aimed at maintaining and improving its effectiveness and economic efficiency are considered. Results from assessing the current technical state of operating boilers, namely, their technical effectiveness and economic efficiency with respect to the standardized and prospective target indicators, are given.

基于质量指标的锅炉机组技术状态评估

摘要-

介绍了详细阐述基于质量指标的锅炉机组技术状态评估方法的结果，包括基于两组指标（环境安全和技术经济效益）的评估。给出了基于所考虑指标的技术状态评估程序。介绍了锅炉单元确定其环境安全并表征其技术有效性和经济效益的主要指标（参数）。给出了指标的加权系数，这些指标以相对单位的幅度反映了各个指标影响技术状态的程度。建议评估设备的技术状态所依据的基本指标（锅炉设备参数的基本值）。特定的向大气排放有害物质的技术标准被用作确定环境安全性的指标的基本值。对于技术有效性和经济效率的指标，可以采用反映操作设备实际可实现的技术有效性和经济效率的标准值，或者确定设备的现代和预期技术可实现要求的指标目标值。对状态进行点和索引评估；指出了得分评估的参考值，并给出了进行状态评估和指数评估的功能依赖性。给出了评估系统的解释，其中包括确定技术状态水平的信息，使用它可以在考虑的质量指标和有害排放物的现有标准之间建立对应关系，并确定设备执行其规定功能的能力。根据技术状态指标的值，考虑了针对主要设备采取的旨在保持和提高其有效性和经济效率的技术措施版本。给出了评估运行中的锅炉当前技术状态的结果，即相对于标准化和预期目标指标的技术有效性和经济效率。根据技术状态指标的值，考虑了针对主要设备采取的旨在保持和提高其有效性和经济效率的技术措施版本。给出了评估运行中的锅炉当前技术状态的结果，即相对于标准化和预期目标指标的技术有效性和经济效率。根据技术状态指标的值，考虑了针对主要设备采取的旨在保持和提高其有效性和经济效率的技术措施版本。给出了评估运行中的锅炉当前技术状态的结果，即相对于标准化和预期目标指标的技术有效性和经济效率。
